Title: Applications of Electron-Interaction Reference Data to the Semiconductor Industry
Published: December 01, 1998
Abstract: Many advanced plasma diagnostic techniques and plasma models require fundamental physical data in order to make accurate measurements or predictions. Fundamental electron-interaction data are among the most critical since electron collisions are the primary source of ions, reactive radicals, and excited species present in etching, cleaning, and decomposition plasmas. In this paper we present (i) a description of some semiconductor applications that require fundamental electron-interaction data, (ii) an explanation of the NIST program to provide these data, (iii) a summary of the available fundamental electron-interaction data for plasma processing gases, and (iv) a discussion of general data needs.
